help, press power button, and nothing happens

[hamdesigns]

ok, i just ordered a new crop of stuff from newegg

assembled it all, plugged in all the wires, closed up the case, plugged in the power line, hit the power button, i hear a slight noise, the power led comes on for an instant, then NOTHING

i tried putting the power supply from my old comp in and it did the same thing, i put my new power supply on my old comp and it did the same thing as whats happening with the new comp

are both my power supply and mother board paperweights?

=(

Did you use spacers? What are your computer specs?

 

[hamdesigns]

im assuming u mean spacers between the mobo and case, and yes i did

sorry, i probably should have listed specs

PSU - Antec 450Watt SmartPower 2.0
Mobo - Gigabyte GA-K8N Pro-SLI ATX AMD Motherboard
CPU - AMD Athlon 64 X2 3800+ 2000MHz HT Socket 939 Dual Core Processor
Video Card - eVGA Geforce 7600GS 256-P2-N549 Video Card
Hard Drives - Seagate Baracudas SATA3.0
DVD Burners - Pioneeer
DDRAM - Corsair XMS 2x1gb

The power supply had a 20+4 conector, so that if the mobo it was going into had a 24 pin input, you could do that

the mobo does have a 24 pin input, so i connected the 4 and 20 and plugged it in

i also plugged in the 4 plug ATX 12V plug into the mobo

there is another plug coming out of the power supply, its a 6 plug and it says "PCI-E" on it, dunno if that has anything to do with it

The 6-pin plug is for PCIe cards that require them and I believe the 7600GS doesn't require them unless you see one on there.

How about the cluster of pins where the case wires fit into... are they put in correctly, especially the power switch... actually sounds like you did though.

Wow, both the PSU and mobo DOA... it's possible. Does your old PSU work on your old computer after all of this?

You want to unhook the optical and the hard drives, use just one RAM, cpu, and hook up power. Don't even need video hooked up, does it work then?

when i put my old power supply back into my old comp i had some issues that i was able to troubleshoot and its all working fine now, as im posting from it, i really dont want to go through it all again though

also, when i turn the power switch on with my NEW power supply, my lights flicker a bit so im guessing its doing something, and my mouse infra red light lights up. And when i turn off the PS with the switch, after a couple seconds i hear a weird sound, like a quick wind down, VERY quick

i just compltely tore down the case and ill try turning it on with just the cpu and ram

 

[hamdesigns]

welp, that doesnt work either

Whoa! You've got an infrared mouse?! Sweet! 😉

If it won't POST with just a CPU, RAM and PSU then (pardon me for stating the obvious 🙂 ) one or more of those parts is bad. It's not a lack of power because that PSU should be plenty for what you've got. It's possible that the PSU from your old computer didn't have the guts to power your new system, making it appear bad. That quick wind down sound is probably a cap discharging or something. You might just have to RMA the parts. 🙁 You could do it one at a time if you want to find out which part was bad or you could do it all at once to get all your working parts sooner.
